Iris and Retina Reader on Your Mobile Phone! How Does It Work?

Iris recognition solutions measure the unique patterns on colored circle around your pupil to identify and authenticate the individual. Some of the best are iris recognition technology deployed in high-yielding areas, such as large international airports. Quickly and without the need to touch any object, the iris recognition is becoming a popular biometric mode also for consumers with regards to incorporate scanners on Photionary and wearable technology in the near future.

Biometric Iris Reader: How It Works?

Iris recognition is a method of identifying people based on unique patterns within the ring-shaped region around the pupil of the eye. The IRIS typically has a brown color, blue, grey or greenish, with complex patterns that are visible after inspection. As an IRIS biometric reader makes use of a biological feature recognition is considered a form of biometric verification.

Iris recognition, the identification process is effected by one or more detailed images of the eye with a sophisticated digital camera, high-resolution, with visible wavelengths or infrared. Then, using a specialized computer program, a corresponding database compares the patterns of the iris of the subject with images stored in a database. Database can compare millions of images per second, with a level of accuracy comparable to conventional fingerprint readers.

Iris Reader is Reliable?

For iris recognition can provide accurate and reliable results, the subject must be within a few meters of the camera. Some control mechanisms should be implemented to ensure that the captured image is a real person, not a high quality photography. The ambient lighting should not produce reflections from the cornea (the bright outer surface of the eyeball), which darken or get in the way of reading any part of the IRIS. The person must remain standing in relation to the camera. Certain types of contact lenses and glasses can obscure the pattern of the IRIS.

Where the Iris Scanner Can Be Used?

Iris recognition, facial recognition, is more often used for safety-related applications. Some countries have implemented iris recognition systems at airports, entry or exit points in institutions and Government buildings. The technology has also been used to prevent unauthorized access to personal computers and mobile devices. Small iris scanner devices and laptops are available for use by consumers, bypassing the need for password entry, or use digital readers. Smartphone cameras, good quality, also have IRIS scanners, and can also be used to make payments, passwords, make logins in email accounts, social networks, and other online services.

Advantages of Using An Iris Scanner

The iris of the eye has been described as the ideal part of the human body for biometric recognition to ensure secure, efficient and fast operations safely, especially at borders, airports, and businesses.

The IRIS is an internal organ that is well protected against damage and wear by a transparent membrane and extremely sensitive (the cornea). This distinguishes it from fingerprints, which can be difficult to recognize after years in certain types of manual labor.

The IRIS has a fine texture that, like fingerprints, is determined randomly during embryonic gestation. Even genetically identical individuals have completely independent IRIS texture.

The iris diaphragm is mostly flat and its geometric configuration is only controlled by two complementary muscles that control the diameter of the pupil. This causes the IRIS has a much more predictable than, for example, the face.

Disadvantages of Using An Iris Scanner

IRIS scanning is a relatively new and expensive technology. The change to this system requires training, time, and investment that many companies and institutions do not yet have. Maybe this will change with the cheaper smartphones using this technology in their cameras.

Iris recognition is very difficult to perform at a distance larger than a few metres. If the person to be identified is not cooperating, it can also be difficult to identify.

As with other photographic biometric technologies, iris recognition is susceptible to poor image quality.

Blind people, no eyes, or with some sort of injury in the IRIS may not have the iris recognition, requiring other means of identification.

Worth Investing in An Iris Scanner?

The iris scanner is accurate and reliable: more accurate than other alternatives of biometric security or otherwise. A standard badge is not susceptible to theft, loss or compromise.

It is also fast and stable, because the iris pattern is formed at 10 months old, and still stable throughout life. The record complete with instruction for use, can take less than 2 minutes. Authentication takes less than 2 seconds.

Readers and IRIS scanners are easily expandable, scalable and flexible. The data stored in an IRIS only requires 512 bytes of storage by IRIS, and even large databases do not compromise the speed of research or impair the accuracy of performance. Works in standalone mode and integrates easily into existing security systems.

Final Considerations

With smartphones like iPhone and Lumia XL 950 making the reading of the IRIS, the public acceptance of IRIS authentication technology tends to increase. It is worth remembering that the reading of IRIS is a different technology of retina, which needs more advanced technology to “read” the blood vessels of the eyes. Another contributing factor to the popularity is the ease of use, and greater safety for the fingerprint readers. Let’s see how this new technology will be accepted in the next few years, as well as other innovations in the world of smartphones, like the watches with Android.

What do you think of the IRIS-reading technology? Would have some use an iris scanner in their day to day?
